Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed November 17, 1913. Serial N o. 801,482.

To all whom t may concern.'

Be it known that I, HENRY R. Corr, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in F ountain-Pens, of whichthe following is a specication.

This invention relates to fountain pens and has for its principal objectto simplify and cheapen the construction and proportionately increasethe durability of the device. In a device of this character, 1ightness,durability and symmetry must be carefully considered in the productionof an mercially. If some of the parts are out of proportion and madeheavier than necessary in order to secure suiicient strength at certainpoints, then the construction is faulty and should be remedied.

Figure l is a side elevation of a device embodying the improvedfeatures. Fig. 2 is a similar view with the sleeve and cappart removed.Fig. 3 is a detached view of the sleeve-part. Fig. 4 is a somewhatenlarged view, showing the sleeve and a portion of the cap-part inlongitudinal section.

As the improvement relates to a single feature, a general description ofthe device will be omitted.

A represents the barrel or body-part, B a sleeve and C a tubular cap.

The barrel is provided with the usual opening 5 for the insertion of alinger in the operation of filling the ink-chamber, and the sleeve Bwith a corresponding opening 6. In this instance the barrelAis providedwith a threaded part 7 and a stop-shoulder 8 located back of the lingeropening 5. The removable sleeve B is provided interiorly and at the rearend 9 with a correspondingly threaded surface 10 to engage the threadedpart 7, as best shown in Fig. 4, the sleeve being in its mounted engagedposition, the

nger opening in the barrel being closed. The sleeve B is also providedinteriorly with a shoulder which comes to a stop against shoulder 8 onthe barrel-part. It will be noted that the inner end of the sleeve hasno threaded connection, having only a close telescopic lit. The exteriorsurface of the barrel, in advance of the finger opening, is free from aweakening shoulder or threaded part at the junction with the inner endl1 of the sleeve and therefore entirely obviating the liability of thebarrel being fractured at that point, and also permit of the barrelbeing made of lighter and therefore thinner material which is also anadvantage. The sleeve B may also be made proportionately lighter. Underthe ordinary conditions when the barrel was provided with a threadedsurface and a stop shoulder in advance of the finger opening for theengagement of the inner end of the sleeve-part, had a tendency to weakenthe barrel at that point and often did result in a fracture. To obviatethis fault the wall of the barrel was thickened which increased thediameter beyond the symmetrical proportions and made the device feelclumsy in the hand.

Another advantage of the present improvement is that the threadedsleeve-parts are in the exact place that is grasped by the lingers inthe operation of manipulating the sleeve in bringing the finger openingsinto and out of coincident relation.

Having thus described my invention, what I claim is 1. In a device ofthe class described, a barrel-member having a finger opening andprovided with a threaded-part and a stopshoulder back of said opening,and a telescoping sleeve member provided with a corresponding openingand having its back end threaded interiorly and provided with astop-shoulder adapted to engage the shoulder on the barrel-member whenthe barrel and sleeve member are joined in a threaded engagement.

2. In a device of the class described, a barrel-member having an openingtherein and provided with a threaded part and stopshoulder back of saidopening, sleeve-member having an opening therein and threaded interiorlyback of the sleeve-opening and provided with a shoulder coming to abearing against said stop-shoulder when the parts are assembled.

In testimony whereof I aiiix my signature in presence of two witnesses.
